QUESTION
I've come across an issue of trying to fade the edges of the background image of a div so that it looks like it's blending with the background image of the full site (so the background image applied to the body).
...ANSWER
Answered 2021-Jun-16 at 02:49You can use the background as gradient where the edges are rgba(0,0,0,0). This way it will smoothly blend with background. But this will not work for images. For images You will have to a div of background color and rgba(0,0,0,0) in gradient with color facing outward.

Recently I've been coding a clicker game and now have run into a problem with the onclick function. What I'm trying to do is on the first click, have it change into certain text, and on the second and third clicks change it to a different text. However, on the fourth click, I'd like it to disappear.
However, it disappears on the third click instead of the fourth click. The third click is supposed to show more text, and then call a function and vamoose. It just disappears. Here is my code:

I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.
Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS is the same as TEMPLATE to config django.core.context_processors.static but when I paste that code, turns in error saying django.core.context_processors.static doesn't exist.
I don't have idea why my javascript' script isn't working.
The configurations are the followings
Settings.py
...ANSWER
Answered 2021-Jun-15 at 18:56Run ‘python manage.py collectstatic’ and try again.
The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.

ANSWER
Answered 2021-Jun-16 at 01:31If you are using vuetify from vue-cli-plugin-vuetify (vue add vuetify), treeshaking and auto component import is enabled by default, by using vuetify-loader.
If you look into the source code of vue-cli-plugin-vuetify, it only uses vuetify-loader if it is present in your package.json. So removing vuetify-loader from package.json should disable this behavior.

QUESTION
So I want to be able to look at a specific week of the year and look at all data in the preceding and following 6 weeks.
WHERE t1.weeknum >= week-6 AND t1.weeknum <=week+6
So if week is 20, I want to return everything between 14 and 26.
The problem is weeks >=47 and <=6. For instance, if week is 4, I want the range to be 50 through 10. Years are a separate dimension and I am including all data regardless of year.
I think this would be similar to a compass heading. Say you are at 350 degrees and turn right 30 degrees. 350+30 = 20 degree bearing.
I'm using SQL Server Express
...ANSWER
Answered 2021-Jun-15 at 20:11The Modulus operator (%) seems to be what you want. Since you are using the range 1 to 52 to represent week numbers you need to shift the range to 0 to 51 while calculating:

I'm currently learning HTML, CSS, and JavaScipt. I'm trying to make a basic project, but I'm having problems with adding a new image on the new card. When I click on the 'add item' button, I create a new card with image. However, when I add another card for the second time, my image from the first card that I created will disappear. Can someone help me on how to fix this solution. Thank you.

Install head
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
